It's not set in the future, it's just a better version of the first map. The first map is pretty old and I had a less logical grasp of street layouts and such. In the updated version, I decided to rectify the odd housing clusters while increasing the number of buildings (it is the Sparrow Clan's primary holding).

One of the reasons I like updating old maps every so often is to a) refine styles and try new things, and b) helps me see the kind of progress I am making.
